To (tZZ whom, it may concern.-

Be it known that 1, GEORGE E. MAoxnY, a citizen of the United States, residing at East Liverpool, in'the'county of Columbiana, State of Ohio, have invented certain new and useful Improvements in Wind Musical Instruments; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to brass wind instruments, and more particularly to the class of cornets, althoughit will be understood that the principles involved may be applied to all classes of brass wind instruments where valves and cooperating pipes are employed for producing the different fundamental tones.

The object of the invention is to provide an arrangement of valve-boxes,valves,and pipes wherein the Wind-passages or air-passages will be without sharp angles.

A further object of the invention is to pro-' vide a construction and arrangement wherein the course of the air in the production of open tones will be similar to the courses in the production of valve-tones, in that all of such courses will include valves and pipes and will be gradual and easy in their deflections, thus producing an instrument wherein all of the tones, both open and'valve, may be produced with the same degree of ease.

Other objects and advantages of the invention will be understood from the following description.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is an elevation showing a cornetelnbodyingthepresentinvention. Fig. 2 is a section on line 2 20f Fig.4 looking downwardly and showing the relative positions of each pair of valve and open tone pipes and the box to which they are connected. Fig. 3 is a vertical section through the first valvebox looking in a direction to bisect the angle of the valve and open tone pipes connected thereto, the valve and open tone pipes being indicated in dotted lines and the valve being Fig. 4 is a view similar shown in elevation. to Fig. 1 and showing the opposite side of the instrument.

Referring now to the drawings, the present instrument comprises the three valve-boxes 5, 6, and 7, in which are mounted in the usual manner the valves 8, 9, and'lO. The boxes 5 and 7 are of the usual length, while the box 6 extends therebelow to permit of connection of the pipe 11 with the rear side of the box, the pipe 11 being adapted for connection ,of a shank and mouthpiece to its free end. From the box 6 extends an arc-shaped pipe 12, the upper end of which is connected to the box, the plane of this pipe including the axis of the box,-while the centers of the lower ends of the pipes 11 and 12 are in the same plane at right angles to the axis of the box. 4 The pipe 12 is spaced from the pipe 11 an angular distance of approximately one hundred and forty-five degrees. Connected to the boxes 6 and 7 directly above the point of connection of pipe 11 to the box 6 is a pipe 13, and spaced an angular distance approximately of one hundred and forty-five degrees from the pipe 13 and connected to the box 7 is a pipe 14, the centers of the upper and lower ends, respectively, of pipes 12 and 14 and the axis of the pipe 13 being in the same plane at right angles to the axes of the boxes 6 and 7. In the same vertical plane with the pipes 13 are pipes 15 and 16, which connect the boxes 6 and 7 and the boxes'5 and 6, respectively. The upper end of the pipe 14 is connected to the box 7, and a corresponding pipe 17 is connected at its upper and lower ends to the box 5. The pipe 17 is displaced an angular distance of substantially one hundred and forty-five degrees from the pipe 16.

Connected to the box 5 is a pipe 18, embracing a tuning-slide 19, said tuning-slide also engaging the pipe 20, which terminates in the bell 21. The valves 8, 9, and 10 have eachfopenings therethrough so arranged that when the valves are all raised or are in their normalpositions the course of the air through the instrument will be through pipe 11, box 6 and valve 9, pipe 12, box 6 and valve 9, pipe 13, box 7 and valve 10, pipe 14, box.7.and valve 10, pipe 15, box 6 and valve9, pipe-16, I

box 5 and valve 8, pipe 17, box 5 and'valve 8, pipe 18 and tuning-slide 19, andthrough pipe 20 to the bell 21. It will be noted upon reference to the drawings that this open-tone air-passage has no angles,the.pipesbeingso arranged that the deflections are curves.

Connected to the valve-box 5 at one side of the pipe 17 is a U-shaped valve-pipe 22, the centers of the ends of which are in the same plane with the centers of the corresponding ends of pipe 17, and when the valve 8, which is the first valve, is pressed downwardly the air from pipe 16 is deflected laterally from the pipe 17 and into the pipe 22, from the lower end of which latter it passes back into the valve-box 5 and through the valve 8 to the pipe 18. To accomplish this result,.the

valve 8 has a pair of openings 23 and 24 there through, and when the valve is in raised position the opening 23 registers with pipes 16 and 17, while the opening 24 registers with pipes 17 and 18. Two other openings 25 and 26 are formed through the valve 8 at higher elevations than the openings 23 and 24:, respectively, and when the valve 8 is depressed the openings 23 and 24 are carried out of registration, while the opening 25 is carried into registration with pipes 16 and 22, while the opening 26 is carried into registration with pipes 22 and 18.

Connected to the valve-box 7 is a valvepipe 27, the upper and lower ends of which are at the same elevations as the upper and lower ends, respectively, of the pipe 14, and the valve 10 has openings therein similar to the openings in the valve 8, so that when the valve is in raised position the path of the air will be through the pipe 14, and when the valve is depressed such path will be through the pipe 27, it being noted, upon reference to Fig. 2, that the angular distances of pipes 22 and 27 from pipes 16 and 15, respectively, are the same as the angular distances of pipes 17 and 14 from pipes 16 and 15, respectively, so that the only result of depressing a valve is to increase the length of the air or wind passage Without changing in any marked degree the character of the passage.

Connected to the valve-box 6 in the same transverse planes with the upper and lower ends of the pipe 12 are the upper and lower ends of a U-shaped pipe 28, and the lower portion of the valve 9 has openings therethrough similar to the openings of the valve 8, so arranged that when the valve is pressed down the wind from pipe 11 will be deflected from pipe 12 into pipe 28, through which it will pass back to the box 6 and valve 9 and thence to pipe 13. Thus with all of the valves raised the air passes through each of the valves and its box and through the U shaped pipe attached to each box, each of the U- shaped pipes deflecting the air laterally to the same degree. As each valve is depressed the air is deflected from the corresponding pipe just mentioned into a similar pipe of a length corresponding to the tones to be produced when such valve is depressed, this second pipe having the same deflection as the first pipe. Thus the air has exactly the same nature of passage through the valves and boxes and pipes when the valves are raised as when they are depressed, the only difference being that when the valve is depressed the air instead of passing from the valve through a short pipe with a given deflection passed through a slightly-longer pipe with the same degree of deflection, but in an opposite direction. There is therefore no more resistance to the passage of the air under one condition than under the other excepting for the slight friction of the slightly-longer pipe. The airpassages being similar, the tones must of course be blown with the same degree of ease.

It will be understood that in practice modifications of the specific constructions shown may be made and that any suitable materials and proportions may be used for the various parts without departing from the spirit of the invention.

WVhat is claimed is- 1. A wind musical instrument comprising three valve-boxes having pipes connecting them, a pipe connected to the second valvebox at a point below the remaining valveboxes and adapted for connection of a mouthpiece with its opposite end, open-tone and valve-tone pipes connected at their lower ends to the second box at the same height with the first-named pipe and connected at their upper ends with the second box at the same height with a pipe connecting the second box with the third box, open-tone and valve-tone pipes for the third box connected to the third box at their lower ends at the same height with said pipe that connects the second and third boxes, and having their upper ends connected to the third box at the same height with a second pipe connecting the second and third boxes, a valve-tone and an open-tone pipe connected at their upper ends to the first box at the same height with a pipe connecting the first and second boxes and having their lower ends connected to the first box at the same height, a bell, and a pipe leading from the bell to the first valvebox at the same height with the lower ends of the connected valve and open tone pipes.

2. A wind musical instrument comprising valve-boxes having pipes connecting them, a valve-tone pipe and an open-tone pipe connected to each of the valve-boxes with their corresponding ends at the same elevations and spaced the same angular distances from said connecting-pipes, and a valve in each box constructed and arranged to connect the valve-tone and open-tone pipes interchangeably with said connecting-pipes.

In testimony whereof I affix my signature in presence of two witnesses.
